MACHINE ron MAKINGWIRE FABRIC.

To alt whom it may concern: 1

Be it known that LAR HU E. BimLow,

a citizen of the United States, residing at lVorcester, in the countyof.VVorcester and Commonwealth of Massachusetts, have invented a new anduseful Improvement in Machines for Making Tire Fabric, of which thefollowing is a specification, accompanied by drawings forming a part ofthe'same.

My present invention relates to a machine for manufacturing what isknown as square-mesh wire fabric, in which a series of stay wires areplaced across and securely united to a series of strand wires, and theobjects of my invention are to providemechanical means for automaticallytraversing astay wire at regular intervals across a series of strandwires, and uniting the stay wire to the strand wires at its points ofjunction therewith by means of twisted loops automatically formed in thestay wire to form a series of rectangular meshes. These objects, amongothers, I accomplish by the construction and arrangement of part ashereinafter described and pointed out in the annexed claims.

In the accompanying drawings, Figure 1 represents a plan view'of amachine embodying my invention. Fig. 2 is a front view of the same. Fig.3 is a front elevation of a portion of the actuatingmechanism shown insectional view on the plane of the broken line 83, Fig. 1. Fig. 4:represents in rear elevation a portion of the actuating mechanism shown,in sectional view on the plane of the broken line M, Fig. 1. Fig. 5 isa transverse sectional view on the vertical plane of one of the twistingheads,illustrating the construction and operation of the loop formingand twisting mechanisms. Figs. 6, 7 and 8 are similar sectional views tothat shown in Fig. 5, but showing the loop forming and twistingmechanisms in different positions assumed during theoperation of formingand twisting a loop of the stay wire. Figs. 9, 10 and 11 areplan viewsof a portion of the loop formin and twisting mechanisms, shown in dierent positions in the different figures. Fig. 12 1s a fro-ntview of theloop forming and twisting mechanisms shown in Fig. 11. Fig. 13 is ahorizontal sectional view through the twisting head and loop-formingjaw, show-- ing the latter in the position of forming the Specificationof Letters Patent.- 1 P t nt d s t 1914 Application filed March 1,19-11. serial No. 611,692.

loop inthe stayiwire. Fig. ltis asectional view of the same, showing thetwisting head advanced to inclose the loop. Fig. 15 is an end view ofone of the twistin heads. Fig. 16 is a detached view of a pair of theactuating gears and stop motion comprised in the takeup ,mechanism. Fig.17 is a detached view ofone of the loops inthe stay wire, showingitsrelation to the strand wire before twisting.

Fig, 18 represents a portion of the completed fabric. .Fig. 19;is adetached view of the mechanism for operating the vertically movable rodsfor taking up the stay wire. Fig. 20 i a detached view of one of theloops in the stay wire formed at the edges of the wire transverselyftothe strand wires, for

forming loops in the stay wire; for twisting the same around the strandwires and for intermittently taking up the completed fabric. Between oneof the end frames and a supplemental frame 1t I support a system ofgearing for actuating the several Inecha- I nisms which operate directlyupon thewire in forming the fabric, said mechanisms being representedupon a larger scale in Fig. 5 which represents the fabric formingmecnanism in connection withone of the strand wires 2. The strand wire .2,afterpassing through a'jseries of straightening rolls 5 and over a whiproll ,6, is. conducted through a hollow spindle 7 which [is journaled ina cross beam 8. The hollow spindle 7 carries upon one end a twistinghead 9 which is normally held againsta vertical plate 10 supported upona cross beam 11 by means of a spiral spring. 12, which is inclosed inarecess in the cross beam 8, between the end wall of the recess and acollar 13 attached to the hollow spindle 7. Atcthe proper period in theoperation of the machine, rotary mo-.

tion is imparted to the twisting head 9 means of a reciprocating rackbar 14, sliding in ways in the beam 8- and engaging a pinion 15 attachedto the spindle 7.

In front of the plate 10 is a loop forming jaw 16, sliding in ways inthe beam 11 and pivotally connected by means of a link 17 with a rockinglever 18 pivoted at its lower end at 19 to the framework of the machine.The lever 18 is connected with a fixed part of the framework by means ofa spring 20, the tension of which serves to normally hold the lever 18in its forward position, as shown in Fig. 5, to maintain the loopforming j aw 16 a short distance in front of the plate 10 to allow atraversing carrier 21 to lay the stay wire 22 upon the strand wires 2between the loop formingjaw'lG and the plate 10. The strand wires 2 passthrough the plate 10 and through a slot in the loop forming jaw 16 to atakeup roll 23. The carrier 21 for the stay wire travels in ways 24, 24in an overhead beam 25 supported upon the end frames 1. A back and forthtraversing movement is imparted to the carrier 21 by means of an endlesschain 26 carried upon sprocket wheels 27, 28 and at tached to thecarrier 21. The stay wire 22 taken from an overhead spool, not shown,passes through the carrier 21 by which it is laid upon the strand wires2 when the loop forming and twisting mechanisms are in the positionshown in Fig. 5. The loop forming jaws 16 are then drawn back throughnotches in the plate 10, pushing the twisting heads 9 into the positionshown in Fig. 6, compressing the spring 12 and forming a loop 29 aroundthe jaw 16, as shown in Fig. 13. This movement of the looping aws isaccomplished by means of cam plates 30 carried upon a cylinder 31 andacting against cam rolls 32 carried by the pivoted levers 18.

The cylinder 31 is provided with a cam plate 30 for each one of thelevers 18, and they are arranged upon the cylinder 31 so as to actconsecutively upon the levers forcing back one lever after another fromone side of the machine to the other, the movement of the leversfollowing thepassage of the carrier 21 across the strand wires. As eachof the cam plates 30 passes the rolls 32,

" their respective levers are again drawn forward by the tension'of thespiral springs 20, allowing the loop forming jaws 16 to passfrom theposition shown in Fig. 6 into the' position shown in Fig. 7. In theposition of the parts shown in Fig. 7, the twisting head 9 is broughtagainst the vertical plate 10 by the tension of the spiral spring 12,andv the loop forming jaw 16, still in contact with the twisting head 9,is held from further forward movement by the contact of ascrew 33,carried in the upper end of the lever 18 with a latch 34 held looselyupon an oscillating shaft 35. The shaft 35 forming members shown inelevation in Fig.

6 is represented on a larger scale in sectional plan view in Fig. 13.The position of the twistingand loop forming members shown in elevationin Fig. 7 is represented on a larger scale in sectional plan view inFig. 14. The loop 29, formed by the rearward movement of the jaw 16through the plate 10, is represented in Fig. 14 as inclosed in adiametrical slot 42 formed in a hardened steel bushing 43 held in thetwisting head 9 by means of a set screw 44. After the carrier 21 haspassed transversely across the strand wires and the series of loops havebeen successively formed and inclosed in the twisting heads in theposition shown in Fig. 14, a reciprocating motion is given to the rackbar 14 which rotates all the twisting heads 9 to carry the two parallelsides 45, 45 of the loops 29 around the strand wires 2. A sufficientnumber of rotations is given to the twisting heads to cause the loops tobe thoroughly twisted around the strand wire, as shown at 46, Fig. 18.As the twisting head 9 is rotated, in the manner above described, theparallel sides 45 of the loop contained within the slot 42 are carriedaround in a common circular path, being maintained 180 apart. Thetwisting of the wire, due to the rotation of the head 9, re-

sults in a longitudinal shortening of the loop 29, the crown of whichgradually moves inwardly, in the direction of the open end of the loop,in response to such shortening. When the twisting operation has beencompleted, the oscillating shaft 35 is rocked to raise the latch 34 fromthe position shown in Figs. 6 and 7 to the position shown in Fig. 5,which releases the lever 18 and allows-the tension of the spring 20 tomove the loop forming jaw still farther forward from the position shownin Fig. 7 to the position shown in Fig. 5, thereby providing suflicientspace between the loop forming aw 16 and the plate 10 to allow thecarrier 21 on its return movement to lay another stay wire upon theseries of strand wires.

v The several sliding'loop forming jaws 16 5. The cams 48, in theposition shown Fig. 5, support the beam:11 with its loop' formingjaws--16 in ,a raised position, butafter the operation ,oftwistinghasbeen performed, a shaft: s9, to which the cams 48 are attached, isrocked, bringing the cams into 5, when the traversing movement of thecarrier 21 is reversed and the levers 18, beginning at the opposite sideof tnemachine, are COIISGClltlVGlY moved back by areverse movement ofthe cam carrying cylinder 31.

The ta'lreup roll 23' isprovided with spurs 50 projecting from itsperiphery, which engage-the stay wires to take up the completedfabricand draw the strand wires 2v through the hollowv spindles '7 vandslots 51 in the loop forming aws 16. As the com: pleted fabric is takenup by the intermittent movement of "the takeup roll 23, itis wound upona winding roll 52. The strand ires are spaced to correspond with thedesired vertical height of the meshes in the coinpleted fabric. In thepresent instance the strand wires are nearer together upon one side ofthe fabric than upon the other, as shown in Figs. 1 and 2, in which thestrand wires are nearer ftogether uponthe left hand. side of thefigures, or upon that side of the fabric Ii which is designed to beplaced nearest" the ground when used as a fence. The horizontal size ofthe meshes is determined by the extent of movement of thetakeiqazroll23. As the direction of the movement of the car: rier 21 ischanged at eachend of its traversing 'movement, the stay wire 22iscarried around the up oer end of a vertical sliding rodhS, one of whichis shown at thelefthand side of the machine in Fig. 12, which rodsnormally project above the top of'the beam' 11. The passage of: the staylwire aroundthe rod 53 provides a surplus length of stay wireavhich istaken up bythe for wardmovement 'of the first loop forming jaw 16. henthe carrier 21 has reached "a position past the first few twistingheads, as shown in Fig. 9, the vertical sliding rod 53 is depressed torelease the stay wire-and allow the slack, shown at 54-, F lg. 9 to bedrawn taut and parallel with the sides of the selvage wire 3 by theformation of the loop-formed by the slidingmovement of the In plan viewinjFig. 9,all twisting The cams 48 are then rotatedto raise'the loopforming ]aws'16. into their normal position, as shown inFig.

heads there represented are shown as being held against theverticalplate 10, with the carrier 21in Fig. 9 is represented as havingjust'begun its traversing movement toward the right and having laid thestay wire upon the strand wires in front of the first three twistingheads upon the left-hand side of the machine, with, they stay wirecarried around thevertical rod 53,, to furnish an extra length of staywire at54 sufficient for the formation of the first loop.

In Fig. 10 the carrier 21 has advanced to the right and laid the staywire in front of the first seven twisting heads at the left side of themachine. The rod 53 is there shown as depressed, which has released thestay wire. All the loop formingwjaws in Fig. 10 have been. movedrearwardly loop forming j aws; 16; drawn forward be- I neath the covers4:? and corresponding to the position-shown 'inelevation in Fig. 5. The70 through notches inIthe -.plate 10 into the position shown in Fig. 6,inorder to form "loops in the stay wire.

ing. heads 9 are represented as havingv been returned into contact withthefvertical plate 10,"said heads 9 andtheir corresponding loopforming'jaws being in positions corresponding to those showninelevation'in Fig. 7 The third twisting head. 9 is represented aspartially returned, while the remaining four twisting heads 9 and theirloop forming jaws are still in the position shown in elevation in Fig.6.

In Fig. 11 the twisting heads "and loop forming jaws are'all shown inthe position represented in Fig.7, or in tllGPOSltlOIl in which thetwistingheads are rotated for the purpose of twisting theloops 29 aroundthe strand wires, which is accomplished by the sliding movement of therack-bar lL- The The first'two twists 1 rack-bar 14- is moved in onedirection for twisting oneset of loops and in'the opposite direction"for twisting the next succeeding set of loops; Theproper movements reimparted to ,the 'diflerent elements directly'concerned in themanufacture of the fab'rlcas abovedescribed by means of power appliedtoa pulley 55 on the short co untersh aft 56. The rotary motion .oftheshaft 56- is applied through thebe'veled pini'onfl57, bevel gear 58,intermediate shaft .59 and yspur gears 60 and 61 to the main drivingshaft 62. .To a

one end of the main shaft 62 is att'achedga segmental gear 63, Fig.2,engaging a segmental gear 64:.attachedto a shaft 65, upon attach asprocket wheel 71 connected by a chain belt 72 with a sprocket wheel 73attached to the hub ofthe sprocket wheel 27. The rotary motion of theshaft 65 is imparted in the same direction to the bevel gear67 and thesprocket wheel 71 when the clutch collar 70 engages the hub of the bevelgear 67 as shown in plan view in Fig. 1. .When the clutch collar 70 isshifted to engage the hub of th bevel gear 66, the shaft 65 will rotatethe bevel gear 67 and sprocket wheel 71 in the opposite directionthrough the miter gear 68. Movement is thereby imparted to the sprocketwheels 27 and 28 in opposite directions to move the stay wire wires. Theshaft 65 is rotated intermit-' tently by the engagement of the segmentalgears 63 and 64, and during the period of rest of the shaft. 65 it islocked from movement by means of the broad tooth 74 riding upon theplain periphery 75 of the segmental gear 63, forming what is known as aGeneva stop motion. The clutch collar 70 is shifted to alternatelyengage the bevel gears: 66 and 67 by means of a shipping lever 76pivoted at its lower end to a fixed stud 7 6*, held in the frame 4 andactuated by a cam 77 engaging a cam roll 7 8 on the lever 76and rotatedfrom the main shaft 62 by thegears 7 9 and 80, Fig. 3.

Attached to the main shaft 62 is a spur gear 81, which engages a gear 82on a shaft 83 to which a cam 84 is attached. The cam 84"acts against camrolls 85 and 86 placed upon diametrically opposite sides to impart areciprocating motion to a bar 87 ,which is connected by a link 88 to oneend of a rock ing lever 89. The rocking lever 89 is provided at itsopposite end with a segmental rack 90, which engages the rack 14 bywhich the twisting heads 9 are rotated. The main shaft 62 also impartsan intermittent motion to a shaft 91 by means of a pair of segmentalgears 92 and 93 which are shown detached in Fig. 16; The driven gear 93is provided with locking teeth 94 and 95', by which the gear is heldfrom rotation during the passage past them of the plain periphery 96 ofthe driving gear 92 forming a Geneva stop motion, by-which the shaft 91is locked between its intermittent motions. The shaft 91 is connected bythe bevel gears 97 and 98 with a short shaft 99, which carries a cam1'00 acting upon the cam rolls 101 and 102 to actuate a rack 103. Therack 103 engages a pinion 104, which is connected by apawl and ratchetmechanism with a shaft 105 upon which the takeup roll 23 is moun ed. Theshort shaft 99 is connected by a chain belt 106 with the shaft 49 uponwhich the cams 48 are carried. The intermittent motion transmittedthrough the segmental gears 92 and 93 is imparted to the takeup roll 23and also to the cams 48 to cause the beam 11 to be depressed and allowthe completed fabric to pass over the covers 47.

The mechanism already described for im-' 'means of a sliding clutchcollar 112, by

which an intermittent motion in opposite directions is imparted to thecam cylinder 31 by nieanslof an intermediate bevel gear 113. The mainshaft 62 carries a cam 114 which actuates a rocking lever 115 connectedby a link 116 with a radial arm 117 on the end of the rocking shaft 35,to impart a motion to the shaft at the proper period to cause its.spline 36 to raise the latches 34 into the position shown in Fig. 5 and,at the proper period, to allowthe latches to be depressed by the spiralsprings 39 into the position shown in Figs. 6 and 7.

' The rising and falling motions of the rods 53, by which, a portion ofthe stay wire is taken up at each end of the traversing movement of thecarrier 21, as already described,

is accomplished by mechanism illustrated in Fig. 5 and more clearly inFig. 19. The lower ends of the rods 53 are pivoted to the freeends ofradial arms 118 carried upon a rock shaft 119, to which a torsionalspring 120 is applied to rock the shaft 119 and hold the rods 53normally in their raised position. Attached to the rocking shaft 119 areradial arms 121 and 122. The free end of the arm 121 is connected by alink 123 with one end of a rocking lever 124, pivoted midway its lengthat 125 and provided at its opposite'end with a cam roll 126 which, atthe proper'period, is acted upon by the cam teeth 127 and 128 upon theshaft of the cam cylinder 31, the tooth 127 rocking the lever when thecylinder is rotated in one direction and the tooth 128 rocking the leverwhen the cylinder is rotated in the opposite direc- 121 to rock theshaft 119 and depress the rods 53 below the top of the beam 11, so asto-releasethe stay wire which had previously been carried around therod. as shown at 54 in Fig. 9. As the rods 53 are depressed, the arm 122is raised and a hooked latch 129 is carried beneath the end of the arm122 by the tension of a spiral'spring 130, thereby locking the rockingshaft 119 against the tension of the torsional spring 120. The lockingof the shaft 119 by the latch 129 prevents the rods 53 from being raiseduntil the latch 129 is released, which is accom plished by means of thecam teeth 131- carried on the shaft 105 of the takeup roll 23 actingagainst a cam roll 132, which is carried by the upper end of the hookedlatch 129, causing the latch to be rocked on its pivot 133 against thetension ofthe spiral spring 130.

The shaft 105 of the takeup roll 23 is connected with the driving powerby a clutch 135, which is normally held in engagement by a spring 136acting upon a shipping lever 187. The lever 137 can be rocked todisengage the clutch by means of a foot treadle, thereby disconnectingthe takeup roll 23 and at the same time allowing the other operations ofthe machine to be carried on, when necessary for any reason, such as thereplacement of a broken stay wire. Motion is imparted to the windingroll 52 from theshaft 105 of the takeup roll by means of gears 139 and achain belt 140 carried upon sprocket wheels 141 and 1&2. The sprocketWheel 1 12 is loose upon the shaft 105, but its web is clamped between adisk 1&3 attachedto the shaft 105 and a slidable disk 11% having aspline connection with the shaft 105. The disk 144 is pressed againstthe web of the sprocket wheel 142 by a spiral spring 14-5, forming afriction clutch of just sufficient power to actuate the winding roll 52to take up the slack in the completed fabric as it is delivered bv thetakeup roll 23. The power of the friction clutch is adjusted by means ofa nut engaging the screw threaded end of the shaft 105 and provided witha hand wheel 146.

The operations of forming and twisting the loops in the stay wire is thesame for the strand wires 2, 2 and the selvage wires 3, 3, but thestrand wires2 pass through theslots 51 in the center of the loop formingjaws 10 bringing them in the center of the loops 29, as shown in Fig.17, while the selvage wires 3 pass outside the loop forming jaws 16bringing them at one side of the loops 29, as shown in Fig. 20.

The slidable loop forming jaw 16, which is shown in perspective on alarger scale in Fig. 2.1, is provided with a hooked face 147 under whichthestay wire is caught as the jaw is moved against it. The crown portionof the loop is formed around the rounded surface 148 while the sides ofthe loop are held in the side'grooves 149. The loop is thereby held inalineinent with the diametrical slot 42 of the twisting head '9. As thejaw is retracted after the formation of a loop, the twisting head 9 isheld in contact withthe tip 150 of the hooked face of the jaw and alsowith the shoulder 151 by the spring 12, which advances the twisting headas fast as the jaw 16 is retracted, thereby securely transferring theloop from the jaws, and means for successively moving relation of thetwisting head 9 and jaw 16 is maintained by means of the latch 34: untilafter the heads 9 have been rotated to twist the loops around the strandwires.
